A very nice story from New Geography about the growth connected to San Francisco’s strong and tech oriented economy.
Despite planning efforts to restrict it, the Bay Area continues to disperse. For decades, nearly all population and employment growth in the San Jose-San Francisco Combined Statistical Area has been in the suburbs, rather than in the core cities of San Francisco and Oakland. The CSA (Note) is composed of seven adjacent metropolitan areas (San Francisco, San Jose, Santa Cruz, Santa Rosa, Vallejo, Napa, and Stockton). A similar expansion also occurred in the New York CSA.
The San Francisco Bay Area is home to two of the three most dense built-up urban areas in the United States, the San Francisco urban area, (6,266 residents per square mile or 2,419 per square kilometer) with the core cities of San Francisco and Oakland and the all-suburban San Jose urban area (5,820 residents per square mile or 2,247 per square kilometer), according to US Census 2010 data. Only the Los Angeles urban area is denser (6,999 per square mile or 2.702 per square kilometer). The more spread out New York urban area trails at 5,319 per square mile (2,054 per square kilometer).
The San Francisco Bay & Central Valley Area
The continuing dispersion was reflected in commuting patterns that developed between 2000 and 2010, with the addition of the Stockton metropolitan area, which is composed of San Joaquin County, with more than 700,000 residents. San Joaquin County is located in the Central Valley and is so far removed from San Francisco Bay that it may be appropriate in the long run to think of the area as the “San Francisco Bay & Central Valley Area.” The distance from Stockton to the closest point shore of San Francisco Bay is 60 miles, and it is nearly another 25 miles to the city of San Francisco.
Ironically, this continued dispersion of jobs and residences is, at least in part, driven by the San Francisco Bay Area’s urban containment land use policies designed to prevent it. What the planners have ignored is the impact on house prices associated with highly restrictive land use planning. The San Francisco metropolitan area and the San Jose metropolitan area are the third and fourth most unaffordable major housing markets out of 85 rated in the recent 10th Annual Demographia International Housing Affordability Survey, trailing only Hong Kong and Vancouver.
